DBA 4000 series T3 Brake Disc 340mm x 30mm Kangaroo Paw DBA42830S - Front

DBA 4000 Series T3 brake discs are a direct replacement performance upgrade for drivers who demand more from their braking system. Designed to perform beyond standard original equipment brake discs, they are ideal for performance road cars, fast road driving, towing and selected track-day applications.

Manufactured from DBA’s XG150 high-carbon alloyed iron, the 4000 Series is engineered to withstand the additional heat and stress produced during repeated hard braking. Thermal Stability Profiling helps improve disc stability and durability, reducing the risk of distortion and cracking under demanding conditions.

T3 Slotted Brake Surface

DBA’s T3 design features 48 precision CNC-machined, tri-symmetrical slots. These additional slots provide multiple exit points for friction dust and gases produced between the brake pad and disc.

The bi-directional slot design helps deliver:

• Quieter and smoother braking
• Responsive pedal feel
• Consistent braking performance
• Improved removal of friction dust and gases
• Universal left or right-hand installation

The non-directional design removes the need for separate left and right brake discs, helping to simplify installation.

Kangaroo Paw Ventilation

Selected vented DBA 4000 Series discs incorporate DBA’s distinctive Kangaroo Paw ventilation system. Instead of conventional straight cooling vanes, this design uses 144 diamond and teardrop-shaped pillars to increase the internal surface area of the disc.

This enhanced ventilation helps to:

• Dissipate heat more efficiently
• Reduce brake fade
• Maintain consistent braking performance
• Prolong brake disc and pad life
• Improve strength under demanding braking conditions

The Kangaroo Paw design can provide up to 20% better cooling efficiency compared with a traditional straight-vane brake disc design.

Thermographic Temperature Monitoring

Thermographic heat paint markings provide a visible indication of the temperatures reached by the brake disc. Each marking changes colour at a specific temperature threshold, helping drivers monitor peak braking temperatures and assess the operating conditions of their braking system.

The markings can also help identify excessive temperatures and support decisions concerning brake pad selection, disc fatigue and replacement.
